Top speed racing is very much like drag racing, but just on a very long track.  In drag racing, it is power to weight ratio which typically determines your performance.  However, when the track is very long, and your vehicle spends much more time at high speed, it is power to drag ratio which is more important.  By drag, I mean primarily aerodynamic drag or wind resistance.  In addition to aerodynamic drag, there is rolling resistance from tires, driveline losses, but the higher the speed, the larger the aerodynamic component of overall drag.
